Application filed December 17, 1907. SerialNo. 106,840.

start, a citizen of the United at San Rafael, State of California, haveinvented a new and useful Improvement in Stream-Power Electric Floats,of which the'following is a specification in States, residing willenable those skilled in the art 'to con- 11163118 for converting theenergy of water electrical energy in a new and improved way.

to the same part apart for platform purposes .to dynamo electricmachinery. Other portions shot wheels 4,

of series of wheels on float.

The same numeral of reference is applied throughout the several v ews. il i In general terms, my invention consists-in combining a float, anundershot Wheel or undershot wheels, a dynamo or dynan'ios, an

OPGIQIUVQ. connection between said wheels and sald dynamos,

and means for securing 'said float In place. y

'It also consists in a novel form of dynamo electric machine, in whichboth the field magnets and the armature revolve relatively toeach'oth'er.

Thedepth to which the .wheels enter the water is deas 3 have spaces left inthem for termined by the strength and depth of the current, and by theproportion thereof which it is desired to utilize.

Letters P .atentof the United An undershot wheel 4 or undershot wheelsare provided, having paddles of suitable form, as, for instance, thatshown in Figs. 1 and 2, be'ing'flat with large surfaces. These wheelsare mounted on a shaft or shafts supported 1n bearings resting on saidfloat.

suitable operative connection is provided between said wheels and adynamo machine or dynamo machines 5 located on said float. The drawingillustrates such, a connection, consisting of a track around thecircumference of said wheels, said track being marked -.7 on thedrawing, and a steel rope or chain 8 connection passing around saidtrack and the. driving pulley of said dynamos. The reason'for usingmetal in-' to enter the water.

Attention is now called to 'the peculiar form of dynamo-electric machinewhich I propose to use with my device, consisting of a rotatablearmature 9 and. alsoa rotatable field magnet 10. The field magnet andarmature are separately mounted,'and a connection from each to thewheels is provided, but in such manner however as to .eau'se each other.The float is secured by means of anchors or attachment to the shore orwharf. If desired a rail 11 may be arranged around the edge of my float;The current generated in my dynamos is carried away in suitableconductors to any point' where it is to be Having. described myinvention, what I claim as new and desire to have secured by States,modifications within the scope of the claims being --reserved, is:

. In a stream-power electric float, a dynamo- I electric machine, havingboth the field ma nets and armature revol-uble, two undershot waterwheels, aconnection from one water wheel to said field magnets, and aconnection from the other water-wheel to said armature.

In testimony whereof;I have set myhand this 10th day'of December A. D.1907, in the 1 presence of the two subscr ibing witnesses. WILLIAM J.PArTosIE Witnesses Y FRANK P. Mniima,
